Hayden Panettiere is single again after reportedly splitting from boyfriend Scotty McKnight.

The actress was first linked to the New York Jets football player shortly after she ended her relationship with Russian boxer Wladimir Klitschko last year, but she has apparently called time on her latest romance.

Sources tell TMZ.com the break-up was completely amicable, with one insider insisting, “They will probably be back together sometime down the road.”

Actress Hayden Panettiere was recently forced to abandon her vegetarian diet because she didn’t have enough energy to power through her workouts.

The former “Heroes” star cut all animals products from her mealtime routine in a bid to get healthy, but the 23-year-old reveals she constantly felt tired and eventually went back to her carnivorous ways.

She tells Self magazine, “I tried vegetarianism, but my body didn’t respond well… I used to run an hour every day… (but) my body shut down. I was low-energy…

“Now I make egg-white scrambles with veggies for breakfast. For lunch, I have chicken or fish and greens, which are good for keeping your system working. I’m a fan of sushi for dinner, as long as the fish aren’t endangered… I can’t be full on a salad.”

“Breaking Bad” star Bryan Cranston has played a big part in actress Hayden Panettiere’s life – he was married to her mom on TV and once hired the young actress for an episode of hit comedy “Malcolm In The Middle.”

During a recent appearance on “Live! with Kelly & Michael,” the actor revealed pretty Panettiere’s mother, Leslie Vogel, played his wife on 1980s and ’90s TV soap “Loving,” and he later cast her daughter.

He says, “I was directing an episode of ‘Malcolm in the Middle’ and Hayden came in and she was supposed to play this kind of nerdy girl, but she’s far too pretty – but she was clearly the best actress.

“So my producer and I were sitting there … and we thought, ‘Maybe if we frizzed her hair up and put glasses on her, we could possibly get away with that.'”

Actress Hayden Panettiere has revealed she became preoccupied with her weight as a teen after her figure was criticized in a magazine.

The “Heroes” star was horrified when she saw an unflattering photo of herself in shorts with the word “cellulite” printed next to her bottom, and the image sent her into a downward spiral, sparking body dysmorphia, a condition which affected the way she saw herself.

She tells Women’s Health magazine, “I was mortified. It gave me such body dysmorphia for so long. But I remember reminding myself that beauty is an opinion, not a fact. And it has always made me feel better.”

The former child star, now 23, has since managed to overcome her demons and she feels more confident than ever about her shape.

She says, “People can tell when you’re happy with being you and when you’re not. It’s only cheesy because it’s true. As I’ve gotten older and grown into my body, I’ve started realizing that the way you carry yourself and that light coming out of your eyes are the most attractive things about you.”

Julia Roberts and Hayden Panettiere reunited on Wednesday night at the Los Angeles premiere of their much-delayed movie “Fireflies in the Garden.”

The drama, which also stars Ryan Reynolds, was first screened at the Berlin Film Festival in 2008 and was subsequently shown in a limited number of European theaters, but it failed to pick up an American distributor.

After three years, the film is finally being shown in U.S. theaters, and the actresses reunited on the red carpet at the Hollywood launch on Wednesday.

Roberts tells ET Online, “A moment like this takes patience and effort. Making a small film is harder than it used to be. (I’m) happy to be here.”

Panettiere adds, “We went to the Berlin Film Festival with it and walked the red carpet there, and the fact that we’re here now celebrating its opening is really cool. It’s a walk through the past.”

The star, 21, has been dating the Russian sportsman, 35, since 2009 but they have now revealed the relationship is over.

Panettiere confirmed the news in a statement, obtained by Germany’s Bunte.de, while the boxer has blamed the split on their struggle to maintain a long-distance relationship.

Panettiere’s statement reads, “While we decided to split, we feel great sympathy and respect for each other and will surely stay close friends.”

Klitschko adds, “We had a great time together. But more and more we realized how difficult it is to maintain a relationship when living on two continents… I cherish Hayden as a person and woman. I’m sure we will stay friends.”

Panettiere previously dated her “Heroes” co-star Milo Ventimiglia. They split in early 2009.

Actress Hayden Panettiere has warned tattoo fans to beware of getting a tattoo in a foreign language – after discovering her Italian ink is spelled incorrectly.

The “Heroes” star got the phrase “live without regrets” inked on her back, in Italian, to remind herself that everyone deals with disappointment and rejection.

However, the blonde actress was shocked to learn the tattoo artist had made a small yet permanent error.

During an appearance on “The View” on Monday, she says, “Here’s the thing, if you’re going to get a tattoo in a language, just don’t ever go to that country. Or a country where anyone speaks that language…

“It’s not like, ‘Oh I wanted (this) and now it says, ‘I love apples’. It’s ‘live without regrets’ but it has one extra ‘i’ and it’s so minor that people who spoke fluent Italian are like, ‘Egh, that looks right.’ And of course I’m reading in a newspaper that it’s wrong…”

But Panettiere has accepted the minor mistake as a lesson learned.

She adds, “So you know what, I’m left to live up to what it means. I’m proud of it!”

Actress Hayden Panettiere didn’t need much coaching to perfect a blood-curdling scream for new movie “Scream 4” – she has been practicing it for much of her life.

The petite star reveals her dad insisted she develop an eardrum-shattering yell – so that she could scare off potential attackers.

The former “Heroes” star says, “I’m a fireman’s daughter … and he always taught me — because I’m such a small girl — that you always have to look like you have somewhere to be and someone’s gonna miss you if you (don’t) get there.

“He used to tell me all the time when I went to the mall with my friends, ‘What do you do if somebody comes up and grabs you?’ He taught me to scream, ‘You’re not my daddy, you’re not my daddy’. So I had a lot of practice screaming, ‘You’re not my daddy’.

Hayden Panettiere was left fearing for her life during a break-in at her home, revealing she locked herself in the bathroom as burglars attempted to smash their way into her house.

The “Heroes” star was home alone when her burglar alarm went off and she decided to hide until police arrived.

She tells E! Online, “It was the scariest moment of my life. The alarm was going off and off and off, but no one was coming. As soon as I knew what was happening, I grabbed my Taser and my cellphone and locked myself in the bathroom. I called a friend that lived close and I called my dad.”

Panettiere eventually climbed out of the bathroom window to make a run for safety and encountered a team of police officers all holding guns.

She adds, “I was sitting and shaking by the toilet, but then was like, ‘S**ew this! I’m not waiting for somebody to come barging in.’ So I crawled out the window.

“I’m running with this Taser in my hand and I run around the corner of the house and I’ve got like seven police with sniper rifles and lasers on me. I’m going, ‘Don’t shoot! Don’t shoot me, please!'”
